SEERSUCKER FABRIC.

SPECIFICATION forming part of Letters Patent No. 369,276, dated August 30, 1887.

Application tiled March 9, 1887. Serial No. 230,194.

(Specimens) To aZZ whom it may concern."

Be itknown that I, JOHN OUMNooK, a citizen of the United States, residing at South Hadley Falls, in the county of Hampshire and State of Massachusetts, have invented new and useful Improvements in Seersucker Fabrics, of which the following is a. specification.

This invention relates to woven fabrics, and to that class thereof commonly known as seersuckers, the object being to produce goods of this class in which the crinkled stripe is made with regular transverse flutes or corrugations, instead of the irregular wavy crinkles which such stripes ordinarily have, and whereby the appearance of said goods is greatly improved, and they are adapted to a finer class of dress-goods than has heretofore been the case.

In the drawings forming part of this specification, Figure l is a. plan view illustrating a piece of woven fabric embodying my improvements. Fig. 2 is a longitudinal section (some what enlarged) through one of the fluted stripes, Fig. 1. Fig. 3 illustrates in plan view the appearance of a piece of seersucker cloth made in the ordinary way as compared with the improved fabric as herein de; scribed, and as shown in Fig. 1.

It is well known to persons skilled in the art of weaving seersuckcr cloth that the slack or crinkled stripe (4 thereof (see Fig. 3) is produced by providing the loom on which said goods are woven with two warp-beams, the beam carrying the warp for the crinkled stripe being given a freer rotary motion thanthe other one, and thereby producing such a slackness of warpyarns in said stripe as produces the crinkle effect in the woven goods. The adjoining stripes, b, of said goods have their warps taken from the beam which holds them under the usual tension.

In carrying out my invention, whereby I produce seersucker clot-h of improved quality by converting the heretofore irregular crinkled stripe in such cloth into one having regular transverse flutes or corrugations, as 3, Figs. 1 and 2, I carry one or more warp-yarns, 4, (two being shown in the drawings,) from the said beam on which certain of the warpyarns are held under a tension into the said crinkled stripe of the goods, whereby said yarns 4 are interwoven under a tension among the other warpyarns of the stripe which are The said tight yarns 4 are interwoven $1 a ck in said crinkled stripe in stitch form, as shown, by suitable harness motion in the loom. Thus a stitch is formed from one side to the other ofthe goods, and the stitches so formed by said tight threads then and there mark the beginning or the end of the transverse flutes or corrugations 3, making the latter of a height proportionate to the length of the stitches and insuring aperfect regularity thereof, as shown in the drawiugs.

By means of the within described improvement in the manufacture of seersucker cloth goods are produced which possess definite characteristics of beauty and attractiveness which it has heretofore been impossible to i1n part to them when the crinkle stripe is left to take haphazard wave forms; and when said stripes are woven in suitable colors the effect of the latter, combined with the novel effect imparted thereto by the said transverse flutings, tucks, or corrugations, is very attractive; and, moreover, by the employment of said improvements in the manufacture of said class of goods their mercantile value is much increased, owing to the displacement of an indefinite finish et'fect by one having a definite appearance and character.

I am aware that it has been proposed to weave agalloon trimming having a body por tion formed in flutes or corrugations by leaving certain of the foundationwvarps below the shed while the weaving of the flute or c0rrngation progresses, and uniting the whole of the warps to form the fabric between the corrugations or flutes. In this case the straight warps are thrown entirely to the back of the fabric, which is essentially different in character from mine.

IVhat I claim as my invention is An improved crinkle-striped fabric having one or more tight warp-yarns running through the crinkle stripe in stitch form, sub stantially in line with the straight warp of the fabric, and thrown to the opposite sides of the fabric alternately, the crinkle stripe being thereby formed into regular transverse flutes or'corrugations practically alike on both surfaces of the fabric, the crinkle stripe being between plain stripes, as usual in secrsuckcr goods, substantially as described.
